What is the best route to take for studying for the Sat 2 tests? should i read as many books as i can or just one? what method did you use? im debating whether or not to buy like 2 or 3 books on chemistry and writing each--should i?

I would start with just one book. You can probably supplement with textbooks from school. I have a few PR SAT II books and they are very good at explaining the tests and how to score well. Definite thumbs up.
